Spring Has Come - March 21, 2021 - Shipspotting

What a welcome sight to see Canadian Coast Guard cutter and buoy tender, Griffon, swapping the winter buoys in Port Huron, Michigan, for the regular season buoys today!

First, Griffon takes up the winter buoy using its onboard crane. (Most of this operation was difficult to see.)



Time to float the summer buoy. You can see how big it is compared to the guys on board.



The buoy is careful set into the water and released. (I'm sure there's more to that process, but I couldn't find more information about it.)



Griffon heads further upbound to swap out another buoy. Apparently, 6-8 a day is a good number to exchange.


I did a bunch of research to try to find out more about why this exchange needs to be done, but could only find this one article about the Chesapeake Bay mentioning that the ice on the water can damage the regular season buoys. The ice can also displace or even submerge the summer buoys, so it is necessary to have the more durable ones in the winter. I presume that this is the same in the Great Lakes, but couldn't find anything else about it.

Note: Boatnerd also hosts shipping news, huge amounts of data about almost any "laker" and even many of the "saltie" visitors - and even a book called "Know Your Ships". I would encourage supporting his great work, especially as he has plans to add more cameras in 2021.
